Adsorption kinetics of plasticizer dibutyl phthalate at the air-water

The adsorption kinetics of plasticizer DBP in water was investigated. Dynamic and equilibrium ST data of aqueous DBP solution were measured using the pendant bubble tensiometer at eighteen DBP concentrations. At C > 6.0 ¡Á 10?8 mol/cm 3 phase separation occurred, indicating that no micelle was formed for DBP in water.

Enhanced esterase activity during the degradation of dibutyl phthalate

Dibutyl phthalate (DBP) is one of the most abundantly produced and used plasticizers and is incorporated into plastic to make it more flexible and malleable. DBP has been found to be an environmental contaminant and reported as an endocrine disruptor. Therefore, it is crucial to develop ecofriendly alternatives to eliminate phthalate pollution.

Fe-Activated Peroxymonosulfate Enhances the Degradation of Dibutyl

Soil contamination by organic compounds has received worldwide concern for decades. Here, we found that dibutyl phthalate (DBP) could be degraded on moist quartz sand (QS, crystal, a typical soil constituent) during stirring, and the removal rate reached 57.2 ¡À 3.1% after 8 h of reaction. The introduction of peroxymonosulfate (PMS) and zerovalent iron (Fe0) substantially improved the
